Abstract
PURPOSE: To attain high durability even under severe conditions of use, by making a rolling-piston-type rotary compressor with a piston of nitrided cast iron and vanes of nitrided sintered steel.
CONSTITUTION: A piston is made of cast iron because it is easy to manufacture from cast iron and that the graphite improves the wear resistance. The piston is caused to undergo nitriding to harden its surface and heighten its fatigue strength. Before the nitriding, the case iron is quenched to improve its durablity. Vanes are preferably made of sintered steel by powder metallurgy. At least the surface of each vane is set at a carbon content of 0.5% or more to resist sliding wear. The vane is caused to undergo nitriding to harden its surface and enhance its fatigue strength. The combination of the piston of nitrided cast iron with the vanes of nitrided steel has higher durability than conventional ones. This results in enabling the increase of compression capability of a compressor.
